A celt is a common prehistoric tool of stone or metal, shaped like a chisel or ax head. This large jade celt demonstrates the spectacular workmanship of Mayan lapidaries. No engravings decorate the work. The brilliant green hues of the jade are allowed to dominate. In Mesoamerica, from the time of the Olmec civilization, the naked blade was identified with agriculture and food, since stone axe heads were used for clearing fields. However, a celt such as this one would have been used in important ritual ceremonies. Celts were also associated with ears of corn, the V-shape being associated with the husk from which the cob emerged. Although jade is generally thought to be green, it can actually be a range of colors. It is believed that jade working began during an extended period of agricultural abundance that allowed the ancient society to dedicate part of its energies toward the cultivation of more artistic pursuits.
